ok so the bike was running up until about an hour ago. when it was running i was already having acceleration problems( full throttle killed the engine i had to build up rpms slow). well all of the sudden it just crapped out on me. now it wont go hardly above idle speed and if i try to give it gas it dies.
on a side note i am using a homemade external gast tank( 2 litre cola bottle, inside of a pen and some extra fuel line). I dont think this should be the problem.
